Fleet Turnover and Old Car Scrap Policies
This paper incorporates owners' decisions to keep, repair or scrap their old vehicles into a simulation model of fleet emissions. This decision depends critically on the owner's perceived value of the vehicle, so we examine the factors affecting owners' valuations of their old vehicles using a unique longitudinal dataset. Willingness to accept for the vehicle is well predicted by mileage and co...
متن کاملOptimisation of simultaneous train formation and car sorting at marshalling yards∗
Efficient and correct freight train marshalling is vital for high quality carload freight transportations. During marshalling, it is desirable that cars are sorted according to their individual drop-off locations in the outbound freight trains. Furthermore, practical limitations such as non-uniform and limited track lengths and the arrival and departure times of trains need to be considered. Th...

15 صفحه اولAnalysis of Car-to-Car Beaconing with Network Coding
Lack of updated information due to a high beacon loss rate is a key challenge in car-to-car beaconing strategies. One potential solution for this issue is to re-broadcast lost beacons. However, the repeated dissemination of each lost beacon is infeasible due to the limited bandwidth of wireless channels. To overcome this limitation, network coding is a promising technique, through which a node ...
